The DG201B/202B analog switches are highly improved versions of the industry-standard DG201A/202. These devices are fabricated in Vishay Siliconix' proprietary silicon gate CMOS process, resulting in lower on-resistance, lower leakage, higher speed, and lower power consumption.
These quad single-pole single-throw switches are designed for a wide variety of applications in telecommunications,instrumentation, process control,computer peripherals, etc.An improved charge injection compensation design minimizes switching transients. The DG201B and DG202B can handle up to 22-V input signals, and have an improved continuous current rating of 30 mA. An epitaxial layer prevents latchup.
